Diving into federated network

With a growing number of infrastructure cloud services, there are many benefits to interconnecting several clouds. However, seamless cloud interoperability is highly desired but not yet easily attainable in the current cloud solutions market. In this paper we address the problem of network monitoring and analysis in a complex federated network environment. Federated cloud networks deal not only with heterogeneous cloud platforms (i.e. OpenStack, AWS, Azure), but also with different virtualization technologies. Moreover, federation of the networks adds complexity, because in addition to the physical infrastructure and virtual networks dimensions, there is a dimension of the federated overlay network spread across clouds.
